Not gon judge since we don't know what started that fight.
Girls rarely swung on boys at my school unless the dude just wouldn't stop...but that was elementary school. Definitely didn't see that shyt in middle or high school.
Once that testosterone kicks in, girls don't realize shyt is like pure cocaine and steroids. Dude was scrawny too. Things could have been REALLY bad if he was a stocky breh and tried to grapple with her. Young ladies don't understand that a breh won't go a full 100% but when he does, shyt is over.
